ABSTRACT:
The present invention includes a gas-permeable, hydrophilic, graphite fuel cell electrode for use in conjunction with an ionomer membrane. The fuel cell electrode includes a roughened, interstitial graphite surface enclosing micropores, upon which is deposited a catalyst for contacting an ionomer membrane. The graphite electrode has a thickness of about 40 microns.
